按類別或作者獲取文章wordpress

Question

我想從特定類別或特定用戶發佈帖子。看來我們在wordpress中只能有AND條件。我知道下面的代碼是錯誤的，但是這是我需要得到 - 我希望所有由特定用戶編寫的帖子或從一個特定的類別

$args = array(
    'posts_per_page' => 10, 
    'offset'   => $PageStart, 
    'query' => array(
    'relation' => 'OR', /* <--    here */ 
    array(
     'author' => 18, 
    ), 
    array(
     'category' => 20, 
     ) 
    ), 
    'orderby'   => 'date', 
    'order'   => 'DESC', 
    'post_type'  => 'post', 
    'post_status'  => 'publish', 

); 
//print_r($args); 
$author_post = get_posts($args); 

請你幫助所有的職位。提前致謝 。

我已經找到解決這個問題，我有一個自定義查詢做了合併兩個數組

SELECT DISTINCT wposts.* 
      FROM $wpdb->posts wposts 
       LEFT JOIN $wpdb->postmeta wpostmeta 
       ON wposts.ID = wpostmeta.post_id 
       LEFT JOIN $wpdb->term_relationships 
       ON (wposts.ID = $wpdb->term_relationships.object_id) 
       LEFT JOIN $wpdb->term_taxonomy 
       ON ($wpdb->term_relationships.term_taxonomy_id 
        = $wpdb->term_taxonomy.term_taxonomy_id) 
       AND wposts.post_status = 'publish' 
       AND $wpdb->term_taxonomy.taxonomy = 'category' 
       AND ($wpdb->term_taxonomy.term_id IN($cat_list) 
       OR wposts.post_author IN ($authors)) 
      ORDER BY wposts.post_date DESC 

其中$ cat_list是一個包含您的類別ID和ID作品的數組，其中包含您的作者ID。希望這會幫助有需要的人。

如果你想同時做get_posts() 2倍試試這個代碼

$args = array(
    'posts_per_page' => 10, 
    'offset'   => $PageStart, 
    'author'  => '18', 
    'orderby'   => 'date', 
    'order'   => 'DESC', 
    'post_type'  => 'post', 
    'post_status'  => 'publish', 

); 
$author_post = get_posts($args); 

$args = array(

    'posts_per_page' => 10, 
    'offset'   => $PageStart, 
    'category'   => '20', 
    'orderby'   => 'date', 
    'order'   => 'DESC', 
    'post_type'  => 'post', 
    'post_status'  => 'publish', 
); 
$category_post = get_posts($args); 
$total_post = array_merge($category_post,$author_post)

。

1. 來自用戶的所有文章 類別
2. 的所有帖子，然後用array_merge()
